We're dividing 228397 by 15 
Our goal is to divide 228397 by 15.

Step 1:
15 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 15

Step 2:
When dividing 22 by 15, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 15 from 22 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 15

Let's proceed to step 3:
When dividing 78 by 15, we get 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 75 from 78 and we're left with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 15

Step 4:
15 can be fit into 33 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 152.0
The remainder is 3 after subtracting 30 from 33.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 15

Going ahead to step 5:
39 divided by 15 is 2 with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 1522.0
Subtracting 30 from 39 leaves us with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 15

Let's proceed to step 6:
15 goes into 97 6 times with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 15226.0
Deduct 90 from 97 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
15 goes into 70 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 15226.4
If we take 60 away from 70, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
100 divided by 15 is 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 15226.46
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 15226.466
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 15226.466 and a remainder of 0.001.
